Why is electricity shown in movies?
This article states that wizards don't use electricity because magic would interfere with electrical items. Can someone add an explanation for wizards using it in the movies? This picture shows Snape reading by the light of a lamp - in the same room where he, Narcissa, and Bellatrix make an Unbreakable Vow with no apparent interference/issues. Lamps can also be seen in pictures of other homes and rooms. UnicornWolf (talk) 11:00, March 2, 2014 (UTC)
